Financial Signals Dashboard: AI-Powered Real-time Stock Analysis with Bright Data MCP Server & Strands Agents SDK

This is a submission for the Bright Data AI Web Access Hackathon

What I Built

I've created the Financial Signals Dashboard - an AI-powered stock analysis platform that generates real-time alpha signals for investment decisions. This system combines the Strands Agent SDK with Bright Data's MCP infrastructure to deliver comprehensive financial analysis that would typically require a team of analysts.

The dashboard solves several critical problems for investors:

1. Information Overload: Financial data is scattered across numerous websites, making comprehensive analysis time-consuming
2. Analysis Complexity: Technical indicators require expertise to interpret correctly
3. Sentiment Tracking: Market sentiment is difficult to quantify across multiple sources
4. Decision Paralysis: Investors struggle to synthesize conflicting signals into actionable recommendations

My solution provides a unified dashboard that:
• Generates clear BUY/SELL/HOLD signals with confidence scores
• Visualizes technical indicators (price, moving averages, RSI)
• Analyzes market sentiment across news and social media
• Provides position sizing recommendations and risk assessments

streamlit run streamlit_app.py

Model Provider Options via Strands Agents SDK

The dashboard supports two model providers:

Amazon Bedrock

• Cloud-based model with high performance
• Requires AWS credentials
• Default option for production use

Ollama

• Local model running on your machine
• Requires Ollama to be installed and running
• Supported models:
  • llama3.1:latest (recommended for tool use)
  • llama3:latest
  • llama3.1:latest
  • llama3:8b
  • llama3:70b
  • mistral:latest
  • mixtral:latest

Note on Ollama Tool Support: Standard Ollama models like llama3:latest don't natively support tools and may return errors like registry.ollama.ai/library/llama3:latest does not support tools (status code: 400). We've implemented a workaround using specialized prompting techniques as discussed in this GitHub issue. For best results with tools, use the llama3.1:latest model which has better tool support.

Security Best Practices

Important: Always treat scraped web content as untrusted data. Never use raw scraped content directly in LLM prompts to avoid potential prompt injection risks. Instead:

• Filter and validate all web data before processing
• Use structured data extraction rather than raw text (web_data tools)

How I Used Bright Data's Infrastructure

The Financial Signals Dashboard leverages Bright Data's MCP infrastructure across all four key actions through the Strands Agent SDK:

1. Discover

The system uses Bright Data's MCP tools to discover relevant financial content across the web. When analyzing a stock ticker, the agent automatically searches for and identifies the most relevant sources:

The Strands Agent automatically discovers relevant financial information using MCP tools

async for event in agent.stream_async(
    f"""Analyze {ticker} stock and provide a concise alpha signal.

    Use the scrape_as_markdown tool to get data from Investing.com for {ticker} instead of using Yahoo Finance.
    Investing.com page aggregates multiple technical indicators and analyst ratings, which are critical for validating signals."""
):
    if "data" in event:
        response += event["data"]

This approach allows the agent to intelligently discover the most relevant financial data sources without hardcoding specific URLs or search queries.

2. Access

The dashboard accesses complex financial websites through Bright Data's infrastructure, which handles anti-bot measures and access challenges seamlessly:

# In financial_signals_agent.py, the agent accesses financial websites through Bright Data MCP
# The agent is instructed to use specific tools for accessing financial data
SYSTEM_PROMPT_OLLAMA = """You are a financial analysis agent specialized in generating alpha signals.
You have access to tools that can help you gather information from the web.

CRITICAL: You MUST use the scrape_as_markdown tool to get the current stock price from Yahoo Finance.
For example: scrape_as_markdown(url="https://finance.yahoo.com/quote/TICKER")
Replace TICKER with the actual stock symbol. This is essential for providing accurate price information."""

The system uses specialized prompting to ensure the agent accesses the right financial websites, even when using models with limited tool support.

3. Extract

The system extracts structured data from various financial sources using Bright Data's MCP tools:

# In streamlit_app.py, the system extracts technical data from the agent's response
def extract_technical_data(text):
    """Extract technical data from signal text for visualization"""
    data = {}

    # Extract price
    price_match = re.search(r'Price:\s*\$?(\d+\.?\d*)', text)
    if price_match:
        try:
            data['price'] = float(price_match.group(1))
        except (ValueError, TypeError):
            data['price'] = None
    else:
        data['price'] = None

    # Extract RSI
    rsi_match = re.search(r'RSI:?\s*(\d+\.?\d*)', text)
    if rsi_match:
        try:
            data['rsi'] = float(rsi_match.group(1))
        except (ValueError, TypeError):
            data['rsi'] = None
    else:
        data['rsi'] = None

The extraction process is robust, handling various data formats and potential errors to ensure reliable financial analysis.

4. Interact

The dashboard interacts with dynamic financial websites through the Strands Agent and Bright Data's MCP tools:

# In sentiment_analysis.py, the agent interacts with financial news sites
SYSTEM_PROMPT_OLLAMA = """You are a financial sentiment analysis agent.
You have access to tools that can help you gather information from the web.

CRITICAL: You MUST use the scrape_as_markdown tool to get sentiment data about stocks.
For example: scrape_as_markdown(url="https://finance.yahoo.com/quote/TICKER")
Replace TICKER with the actual stock symbol. This is essential for providing accurate sentiment information.

When you need to use a tool, follow this exact format:
<tool>
name: scrape_as_markdown
parameters:
  url: "https://finance.yahoo.com/quote/TICKER"
</tool>"""

The agent is specifically instructed to interact with financial websites in a way that mimics human browsing behavior, enabling it to extract sentiment data from dynamic, JavaScript-rendered pages.

The integration of Bright Data's MCP with the Strands Agent SDK creates a powerful system that can navigate the complex financial web, extract meaningful data, and transform it into actionable investment signals - all without requiring manual intervention or hardcoded scraping logic.

Challenges and Solutions

Challenge 1: Tool Support in Different Models

Some models like standard Ollama models don't natively support tools and returned errors like registry.ollama.ai/library/llama3:latest does not support tools (status code: 400).

Solution: Implemented specialized prompting techniques and XML-style tool calling format as a workaround, and added support for multiple model providers (AWS Bedrock and Ollama).

Challenge 2: Extracting Structured Data from Diverse Sources

Financial websites use different formats and structures for presenting data.

Solution: Created robust regex patterns and extraction functions that can handle variations in data presentation across different sources.

Challenge 3: Real-time Updates Without API Rate Limits

Frequent API calls to financial data providers often trigger rate limits.

Solution: Leveraged Bright Data's infrastructure to access the same data directly from websites without hitting API rate limits, enabling more frequent updates.

Future Enhancements

The Financial Signals Dashboard has significant potential for expansion:

1. Portfolio Management: Analyze multiple stocks and provide portfolio-level recommendations
2. Historical Signal Tracking: Track the accuracy of past signals to improve future recommendations
3. Custom Alert Settings: Allow users to set custom alert thresholds for specific indicators
4. Export Functionality: Enable exporting of analysis reports for offline review
5. User Accounts: Save analysis history and preferences for returning users

Conclusion

The Financial Signals Dashboard demonstrates how Bright Data's infrastructure can transform AI-powered financial analysis. By enabling comprehensive web data access, the system provides investors with professional-grade analysis that would typically require expensive subscriptions and financial expertise.
